During a BBL, how can a fat embolism be prevented?

Fat embolism will always be a risk when conducting a BBL. That being said, they are very rare. Fat injection can happen two different ways; injection into the gluteus muscle and injection into the existing buttocks fat. The gluteus muscle is what contains the blood vessels your plastic surgeon will want to stay away from, and there are several techniques he will use to do so. First his grafting instrument should be tipped with a blunt end, with the hole releasing the tissue on the bottom end of the tip - the blunt edge allows the tool to move blood vessels out of the way instead of puncturing them. Secondly all tissue deposits are done superficially; which means the tissue is injected on top of the layers already there, instead of deeper inside the fat and muscle layers. Lastly, the surgeon should employ a retracting motion with his tool while injecting the tissue - keeping him clear of any blood vessels even further. I suggest finding a board certified plastic surgeon that has plentiful experience in BBL's. Consult with him or her and I'm confident you will feel at ease. They are rare. SAFETY and more SAFETY is every surgeons top concern. Best wishes.

This is a very important question to ask your surgeon as this can be potentially fatal complication from BBL. There are multiple kinds of embolism. The two we are most concerned with are fat and venous emboli. To prevent venous emboli, the first key is to find a qualified plastic surgeon for your procedure. Discuss any personal or family history of blood clots and bleeding issues. Before and during your surgery, ensure that sequential devices and compression stockings are on your legs. After surgery make sure that you keep the compression devices on and move frequently. Your surgeon may decide to place you on a low dose aspirin or blood thinner.Regarding fat emboli, again choose a qualified surgeon. There is little that you can personally do to avoid fat emboli as this is a by-product of the fat re-injection technique. I personally believe that using larger cannula's with low dose injections help avoid this problem (the veins are smaller than the injection cannula which helps avoid inadvertent intravenous injection).
